EARL BARNEY, OF SCHENECTADY, NEV YORK.

POULTRY-BROODER.

SPECIFICATION forming part of Letters Patent No. 471,460, dated March22, 1892. Application iiled May 4, 1891. Serial No. 391,464. (No model.)

.To all whom it may concern:

Be it known that I, EARL BARNEY, of Schenectady,in the county ofSchenectadyand State of New York, have invented anew and ImprovedPoultry-Brooder, of which the following is a full, clear, and exactdescription.

My invention relates to improvements in brooders or artificial mothers;and the object of my invention is to produce a broeder for chickens,which will as nearly as possible conform to the laws of nature inbrooding chickens, and will keep them provided with the requisite amountof heat and moisture, and which is also adapted to give them thenecessary chance for exercise.

A further object of my invention is to construct the broeder in such amanner that it may be easily taken down or set up, so that it is Welladapted for shipment.

To this end my inventionconsists in certain features of construction andcombinations of parts, which will be hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar figures of reference indicatecorresponding parts in all the figures.

Figure 1 is a broken perspective viewof the brooder embodying myinvention, portions vof the Wall being removed to show its interiorconstruction. Fig. 2 is a vertical cross-section of the same. Fig. 31san enlarged broken detail view showing the manner in which the bottomand side walls are connected. Fig. 4 is an enlarged detail View showingthecorner construction of ther brooder, and Fig. 5 is a broken plan ofthe united corners.

The brooder is provided with a main coop 10, which is only heated by theWaste heat from the brooding-chamber 11, and this chamber is a sort ofsupplemental room built onto the back of the main coop and provided witha suitable door 11a at the back. The side walls 12 of the coop andbrooding-chamber are united in the following manner: One of the sides isprovided near the corner with a vertical stud 13, which is iirmlysecured to it,

and secured to this stud at intervals are clips 14, which extend towardthe ends of the Wall and which at their extreme ends are bent in= Ward,as shown at 15, the bent portion being made to nearly touch the sidewall. The adjacent side wall12 is provided with a stud 1G, which i'sarranged near the edge of the Wall and which is cut away on the innerside, as shown at 17, thus forming a recess to receive the bent ends 15of the clips 14. It will thus be seen that the clips may be placed inposition upon the stud 17, and the thickness of the stud is such thatWhen the parts are locked together in this way the outer edge of thestud 16 Will bear against the side of the stud 13, as best shown in Fig.5.

The floor of the brooder 18 is provided near the edges and at intervalswith plates 19,which are inlaid in the floor and which have keyholeslots 20 therein, and secured to the bot-- tom of uprights 2l on theside Walls 12 are headed lugs 22, Which project slightly from thebottoms of the uprights and the ends of which are adapted to enter thelarger portion of the key-hole slots 20. The side Walls and uprights maythen be pushed slightly along the floor, so that the Shanks of the lugsWill enter the narrow portion of the key-hole slots, and the walls andfloor will then be locked securely together.

The main cooplO and the brooding-chamber 1l are separated by a verticalpartition 23, and extending diagonally from the lower portion of thispartition to the floor of the main coop is a partition 24, which thusforms an airspace between it and the partition 23, as best shown in Fig.2. This air-space is supplied with air from outside the brooder, the airentering through an opening 24.n in the side of the brooder, and openingfrom the air cham'- ber or space into the ,broodingchamber are apertures25, so that the pure air which enters the air-space may pass throughinto the brooding-chamber. The outlet for the air is through the maincoop and the openings 25 in the upper portions of the same. Y

A brooding tray or frame 26 of common construction is supported in thebrooding-chamber 11, and this tray communicates with the main chamber 10by means of a curtained aperture 27, and the chicks which are supportedon the tray may pass through the aperture and beneath the curtains andover the partition 24. l

On the outside of the brooding-chamber and at one end is a boiler-house28, which contains a heater or boiler 29, and any suitableheaterorboiler maybe employed. The boiler is connected withcirculation-pipes 30, 31,and 32, which extend longitudinally through thebrooding-chamber, the pipe 30 being arranged above the brooding-tray 2G,the pipes 32 beneath the tray, and the pipes 3l being arrangedvertically at one end to connect the pipe 30 with the pipes 32. At eachend of the heating apparatus are extension -pipes 33, one of whichconnects with a boiler and extends upward through the boiler-house andterminates in a cap and the other of which connects with the upper endof the pipe 3l an d extends upward through it, and air-spaces are leftin the upper portions of the pipes 33, and the air thus contained inthese pipes serves as a cushion, as when the water is heated and flowsupward into the pipe the air will be compressed, and as it is elastic itwill react on the air, thus causing a series of pulsations which causesthe air to circulate freely through the pipes.

Beneath the brooding-tray 2 6 and supported upon the pipes 32 are largefiat tanks awhich are lled with water, and the heat from beneath causesthe water to evaporate slowly, and the air which enters through theapertures 25 and passes up through the broodingchamber will thus beproperly laden with moisture.

It will be noticed from the foregoing description that the air willenter the lower portion of the brooding-chamber through the apertures 25and that it will pass from thence into the main coop and then outthrough the openings la in the upper portion of the coop. The chickswhich are in the brooding-chamber will thus be constantly supplied withpure air, and as a portion of the heat is applied to the chamber fromabove and a portion from beneath the heat will be applied to the chicksmuch as if they were hovered by a hen, and as a result they willflourish nicely. It will be noticed, too, that the main coop is suppliedwith heat from the broodin gchamber only, so that it will 4becomparatively cool and the chicks when they pass from the broodingtraywill thus be provided with a suitable place for exercise. Here, again,the broodcr imitates nature, as the chicks will go into the warmerbrooding-chamber to rest.

l have shown in the drawings an individual brooder; but the principle ofmy invention is the same when applied to a large broodinghouse, as thecoop and brooding-chamber may be made of any desired length and the airand heat may be supplied to the chamber in the manner described.

Having thus fully described myinvention, l claim as new and desire tosecure by Letters Patent- A brooder comprising a main coop having anair-outlet in the upper portion, a broodingchamber connected therewith,a tray sup-- ported centrally in the chamber and communieating with thecoop, heat-circulation pipes arranged over and below the tray,moisturetanks arranged between the lower pipes and the tray, and anair-inlet in the lower portion of the chamber, substantially asdescribed.
